I have reinstalled my old copy of GRAW thanks to the nostalgia and boredom, invited some of my friends to play with me (the same friends with whom i used to play with no problem at all), but COOP mode will just not run.
Heres the wierd thing :
In lobby chat, our pings are flawless. 60, 70, 90. No delay, no problems, nothing. If we pick Deathmatch mode, the game runs flawlessly, no lag at all. However, if we pick COOP mode (or any mode that includes NPCs) , my connection will have a huge burst of delay, where it will take me 7 seconds to send a message, and eventually, get disconnected from the server, not even making it through the weapon selection screen (im not the host, btw) Yes, we are using hamachi. The other wierd thing is that whenever we join a COOP match, suddenly i cant ping no one on hamachi, and my modem goes berserk (which is the same modem i used to play back then)
Also, i can play the campaing perfectly fine on single player (on the highest settings without lag), and i really have no idea how to solve this problem.
